Bitumen binders are sticky materials that contain bitumen, which may be in the form of regular bitumen, modified bitumen, or bitumen emulsion.
Bitumen binder has the property of being sticky and waterproof at the same time in other materials and also Bitumen is a binding agent produced from petroleum.
Bitumen is known for being strongly adhesive and resistant to damage from water and oil spills. This makes bitumen the ideal binder for asphalt because asphalt is commonly used as a surface for roads, car parks and driveways.
The term bitumen is often used incorrectly to describe asphalt. On a road sealed with bitumen, a layer of bitumen is sprinkled and then covered with aggregate. This is then repeated to create a two-layer seal.
Durability is Most important property for asphalt binder
Typically, the most important physical properties are: Durability. It is a measure of how asphalt binder physical properties change with age (sometimes called age hardening). In general, as an asphalt binder ages, its viscosity increases and it becomes more stiff and brittle.
The different types of bitumen binders that used in sprayed seals include:
polymer modified binders. elastomeric polymer types. crumb rubber.
specialty binders (e.g. bitumen extended epoxy, polyurethane, acrylic). flexible quick drying coating which is waterproof, weatherproof and corrosion resistant.
